coverageAggregate don't find subprojects

[catena2w]

I'm trying to build aggregate report for https://github.com/ScorexProject/Scorex project. I run commands:

sbt clean coverage test
sbt coverage test

After that I see all coverage data in target directories. I can also build report for each subproject separately, e.g. sbt "project basics" "coverageReport" creates good report for basics subproject.
Now I want to create aggregated report, I run sbt coverageAggregate, but it includes only reports from root project (from target folder only, ignoring scorex-basics/target, scorex-transactions/target etc.).
How to create aggregated report for all of my subprojects?

Check this PR.

I can generate aggregated coverage for your project, if I have coverage reports` for at least two files generated before. Can you confirm my observation?
